Features of your vehicle
Smart key precautions
The smart key will not work if anyof the following occur:
- The smart key is close to a radio transmitter such as a radio sta-
tion or an airport which can inter-
fere with normal operation of the
smart key.
- The smart key is near a mobile two way radio system or a cellu-
lar phone.
- Another vehicle’s smart key is being operated close to your
vehicle.
When the smart key does not work correctly, open and close the door
with the mechanical key and contact
an authorized Kia dealer. If the smart key is in close proximi-
ty to your cell phone or smart
phone, the signal from the smart
key could be blocked by normal
operation of your cell phone or
smart phone. This is especially
important when the phone is active
such as making calls, receiving
calls, text messaging, and/or send-
ing/receiving emails. Avoid placing
the smart key and your cell phone
or smart phone in the same pants
or jacket pocket and maintain ade-
quate distance between the two
devices.
✽ ✽ NOTICE
If the keyless entry system is inoper-
ative due to exposure to water or liq-
uids, it will not be covered by your
manufacturer’s vehicle warranty.
Battery replacement
A smart key battery should last for
several years, but if the smart key is
not working properly, try replacing
the battery with a new one. If you are
unsure how to use your smart key or
replace the battery, contact an
authorized Kia dealer.
1. Remove the mechanical key.
2. Pry open the rear cover.
3. Replace the battery with a new
battery (CR2032). When replacing
the battery, make sure the battery
is in the correct position.
CAUTION - Transmitter
Keep the transmitter away fromwater or any liquid, as it canbecome damaged and not func-tion properly.

FUSES
❈Left side : Normal , Right side : Blown
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will melt.
If the electrical system does not
work, first check the driver’s side
fuse panel.
Always replace a blown fuse with
one of the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized Kia
dealer.
Three kinds of fuses are used: blade
type for lower amperage rating, car-tridge type, and multi fuse for higheramperage ratings.
Do not arbitrarily modify or add-on electric wiring to the vehicle.
WARNING- Fuse replace-
ment
Never replace a fuse with any- thing but another fuse of the
same rating.
A higher capacity fuse could cause damage and possibly a
fire.
Never install a wire or alu- minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
a possible fire.
CAUTION
Do not use a screwdriver or anyother metal object to removefuses because it may cause ashort circuit and damage thesystem.

✽ ✽
NOTICE
• When replacing a fuse, turn the
ignition “OFF” and turn off
switches of all electrical devices
then remove battery (-) terminal.
• The actual fuse/relay panel label may differ from equipped items.
WARNING- Electrical Fire
Always ensure replacements
fuses and relays are securely
fastened when installed. Failure
to do so can result in a vehicle
fire.
CAUTION
When replacing a blown fuse or relay, make sure the newfuse or relay fits tightly intothe clips. Failure to tightlyinstall the fuse or relay maycause damage to the wiringand electric systems.
Do not remove fuses, relays and terminals fastened withbolts or nuts. The fuses, relaysand terminals may not be fas-tened correctly which maycause vehicle damage.
CAUTION
Do not input any other objects except fuses or relays intofuse/relay terminals, such as adriver or wiring. It may causecontact failure and systemmalfunction.
Do not plug in screwdrivers or aftermarket wiring into the ter-minal originally designed forfuse and relays only. The elec-trical system and wiring of thevehicle interior may be dam-aged or burned due to contactfailure.
If you directly connect the wire on the taillight or replacethe bulb which is over the reg-ulated capacity to install trail-ers, etc., the inner junctionblock can get burned.

Engine compartment fuse
replacement
1. Turn the engine start/stop buttonto the OFF position and all other
switches off.
2. Remove the fuse panel cover by pressing the tab and pulling the
cover up. When the blade type
fuse is disconnected, remove it by
using the clip designed for chang-
ing fuses located in the engine
compartment fuse box. Upon
removal, securely insert a reserve
fuse of the same rating. 3. Check the removed fuse; replace it
if it is blown. To remove or insert
the fuse, use the fuse puller in the
engine compartment fuse panel.
4. Push in a new fuse of the same rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorized Kia dealer.
Multi fuse
If the multi fuse is blown, it must be
removed as follows:
1. Turn off the engine.
2. Disconnect the negative batterycable.
3. Remove the nuts shown in the pic- ture above.
4. Replace the fuse with a new one of the same rating.
5. Reverse these steps to reinstall the multi fuse.OJFH075025

LIGHT BULBS
Bulb replacement precaution
Please keep extra bulbs on hand
with appropriate wattage ratings in
case of emergencies.
Refer to “Bulb Wattage” in chapter 8.
When changing lamps, first turn off
the engine at a safe place, firmly
apply the parking brake and detach
the battery’s negative (-) terminal.
Use only bulbs of the specifiedwattage. net-work failure
The headlamp, taillight, and fog light
may light up when the head lamp
switch is turned ON, and not light up
when the taillight or for light switch is
turned ON. This may be cause by net-
work failure or vehicle electrical control
system malfunction. If there is a prob-
lem, we recommend the system be
serviced by an authorized Kia dealer.
trical control system stabilization
A normally functioning lamp may
flicker momentarily. This momentary
occurrence is due to the stabilization
function of the vehicle's electrical
control system. If the lamp stops
flickering after a few moments, the
vehicle does not require service.
However, if the lamp goes out after
the momentary flickering, or the flick-
ering continues, we recommend the
system be serviced by an authorized
Kia dealer.
WARNING- Working on the lights
Prior to working on the lights,
firmly apply the parking brake,
ensure that the engine
start/stop button is in OFF posi-
tion and turn off the lights to
avoid sudden movement of the
vehicle that may cause burning
your fingers or receiving an
electric shock.
CAUTION -Light replace-
ment
Be sure to replace the burned- out bulb with one of the samewattage rating. Otherwise, itmay cause damage to the fuseor electric wiring system.
CAUTION -Headlamp
Lens
To prevent damage, do notclean the headlamp lens withchemical solvents or strongdetergents.
